Technical Field

[0003]

[0011] Generally speaking, aspects of the disclosure relate to wireless communications and to techniques and apparatus for handling conflicts between access links and sidelinks. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard released by the Third Generation Partnership Project (3GPP).

[0005] A wireless communication network may include multiple base stations (BSs) that can support communications for multiple user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to a communication link from a BS to a UE, while an uplink (or reverse link) refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, region, and even global level. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard released by the Third Generation Partnership Project (3GPP). NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), so as to better support mobile broadband Internet access, as well as support beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0033] The following is a more complete description of various aspects of the present disclosure with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. More specifically, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether the aspect is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect. For example, using any number of aspects set forth herein, a device can be implemented or a method can be implemented. In addition, the scope of the present disclosure is intended to cover such a device or method implemented using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0034] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0035] It should be noted that although various aspects may be described herein using terms commonly associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied to communication systems based on other generations, such as 5G and later (including NR technology).

[0036] Figure 11 is a diagram showing a wireless network 100 in which various aspects of the present disclosure may be implemented. The wireless network 100 may be an LTE network or some other wireless network (e.g., a 5G or NR network). The wireless network 100 may include a plurality of BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0037] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0038] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections, virtual networks, and / or similar interfaces using any suitable transport networks).

[0039] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that is capable of relaying transmissions for other UEs. Figure 1 In the example shown in FIG. 1 , a relay station 110 d may communicate with a macro BS 110 a and a UE 120 d to facilitate communication between the BS 110 a and the UE 120 d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0040] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0041] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0042] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), an entertainment device (e.g., a music or video device, or a satellite radio unit, etc.), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0043] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide a connection to or to a network (e.g., a wide area network such as the Internet or a cellular network) via, for example, a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component, a memory component, etc.).

[0044] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0045] In some aspects, two or more slave entities (such as two or more UEs 120 (e.g., shown as UE 120a and UE 120e), two or more integrated access and backhaul (IAB) nodes, and / or other types of wireless communication devices) may communicate directly using one or more sidelink channels (e.g., without using the base station 110 as an intermediary to communicate with each other). For example, the two or more slave entities may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, the two or more slave entities may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110. The two or more slave entities may communicate on the sidelink channel using wireless sidelink communication. "Sidelink communication" may refer to communication sent from one slave entity to another slave entity (e.g., UE to UE or IAB node to IAB node) without relaying the communication through a scheduling entity (e.g., BS or IAB donor), even though the scheduling entity may be used for scheduling or control purposes. In some examples, sidelink communications may be sent using licensed spectrum, unlicensed spectrum, such as the Industrial, Scientific, and Medical (ISM) radio band (e.g., 5 GHz), which is reserved for purposes other than cellular communications such as Wi-Fi.

[0046] As noted above, Figure 1 is provided as an example. Other examples may differ from those described above. Figure 1 Examples described.

[0047] Figure 2 Base station 110 and UE 120 (which may be Figure 1 1. Block diagram of a design 200 of a base station in a base station and a UE in a UE. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0048] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, a synchronization signal may be generated using position coding to transmit additional information.

[0049] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0050] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0051] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components in the base station 110 may perform one or more techniques associated with handling conflicts between access links and sidelinks, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in may perform or direct e.g. Fig. 9 The process of 900 Fig.10 The process of 1000 Fig.11 Process 1100, Fig.12 The operations of the process 1200 and / or other processes as described herein. The memories 242 and 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors of the base station 110 and / or the UE 120, may perform or direct, for example, Fig. 9 The process of 900 Fig.10 The process of 1000 Fig.11 Process 1100, Fig.12 The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0052] In some aspects, UE 120 may include: means for detecting a conflict between transmission of an uplink communication associated with UE 120 and transmission of a sidelink communication associated with UE 120; means for sending at least one of the uplink communication or the sidelink communication based at least in part on detecting the conflict, based at least in part on a priority associated with the uplink communication and a priority associated with the sidelink communication; etc. In some aspects, UE 120 may include: means for detecting a conflict between reception of a downlink communication associated with UE 120 and reception of a sidelink communication associated with UE 120; means for receiving the downlink communication or the sidelink communication based at least in part on detecting the conflict, based at least in part on a priority associated with the downlink communication and a priority associated with the sidelink communication; etc. In some aspects, UE 120 may include: means for detecting a conflict between transmission of uplink communications associated with UE 120 and reception of sidelink communications associated with UE 120; means for sending uplink communications or receiving sidelink communications based at least in part on detecting the conflict and at least in part on a priority associated with the uplink communications and a priority associated with the sidelink communications; etc. In some aspects, UE 120 may include: means for detecting a conflict between reception of downlink communications associated with UE 120 and transmission of sidelink communications associated with UE 120; means for receiving downlink communications or sending sidelink communications based at least in part on detecting the conflict and at least in part on a priority associated with the downlink communications and a priority associated with the sidelink communications; etc. In some aspects, such means may include a combination of Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

The transmission timeline for each of the downlink and uplink may be divided into units of radio frames (sometimes referred to as frames). Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be divided into a set of Z (Z ≥ 1) subframes (e.g., with indices from 0 to Z-1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of time slots (e.g., Figure 3A Each subframe 2 is shown in m time slots, where m is the number scheme used for transmission, such as 0, 1, 2, 3, 4, etc.). Each time slot may include a set of L symbol periods. For example, each time slot may include fourteen symbol periods (e.g., Figure 3A ), seven symbol periods, or another number of symbol periods. In the case where a subframe includes two slots (e.g., when m=1), the subframe may include 2L symbol periods, where the 2L symbol periods in each subframe may be assigned indices from 0 to 2L-1. In some aspects, the scheduling unit for FDD may be frame-based, subframe-based, slot-based, symbol-based, etc.

[0055] Although some techniques are described herein in conjunction with frames, subframes, time slots, etc., these techniques may also be applied to other types of wireless communication structures, which may be referred to in 5G NR using terms other than "frames," "subframes," "time slots," etc. In some aspects, a wireless communication structure may refer to a periodic, time-delimited communication unit defined by a wireless communication standard and / or protocol. Additionally or alternatively, a wireless communication structure may be used in conjunction with a wireless communication standard and / or protocol. Figure 3A The configurations of the wireless communication structures are different from those shown in FIG.

[0056] In some telecommunications (e.g., NR), a base station may send synchronization signals. For example, a base station may send a primary synchronization signal (PSS), a secondary synchronization signal (SSS), etc. on the downlink for each cell supported by the base station. The PSS and SSS may be used by the UE for cell search and acquisition. For example, the PSS may be used by the UE to determine symbol timing, and the SSS may be used by the UE to determine a physical cell identifier and frame timing associated with the base station. The base station may also send a physical broadcast channel (PBCH). The PBCH may carry certain system information, such as system information that supports initial access by the UE.

[0057] In some aspects, a base station may send a PSS, SSS, and / or PBCH according to a synchronization communication level (e.g., a synchronization signal (SS) level) including multiple synchronization communications (e.g., SS blocks), as described below in conjunction with Figure 3B Described.

[0058] Figure 3B is a block diagram conceptually illustrating an example SS hierarchy, which is an example of a synchronous communication hierarchy. Figure 3B As shown in , the SS hierarchy may include an SS burst set, which may include multiple SS bursts (identified as SS burst 0 to SS burst B-1, where B is the maximum number of repetitions of the SS burst that can be sent by the base station). As further shown, each SS burst may include one or more SS blocks (identified as SS block 0 to SS block (b max_SS-1 ), where b max_SS-1 is the maximum number of SS blocks that can be carried by an SS burst). In some aspects, different SS blocks may be beamformed in different ways. A wireless node may send a set of SS bursts periodically, such as every X milliseconds, such as Figure 3B In some aspects, the SS burst set may have a fixed or dynamic length. Figure 3B is shown as Y milliseconds.

[0059] Figure 3B The SS burst set shown in is an example of a synchronous communication set, and other synchronous communication sets can be used in conjunction with the techniques described herein. In addition, Figure 3B The SS blocks shown in are examples of synchronous communications, and other synchronous communications may be used in conjunction with the techniques described herein.

[0060] In some aspects, an SS block includes resources that carry PSS, SSS, PBCH, and / or other synchronization signals (e.g., a third synchronization signal (TSS)) and / or synchronization channels. In some aspects, multiple SS blocks are included in an SS burst, and the PSS, SSS, and / or PBCH may be the same between each SS block of the SS burst. In some aspects, a single SS block may be included in an SS burst. In some aspects, an SS block may be at least four symbol periods in length, with each symbol carrying one or more of the PSS (e.g., occupying one symbol), the SSS (e.g., occupying one symbol), and / or the PBCH (e.g., occupying two symbols).

[0061] In some aspects, such as Figure 3B As shown in , the symbols of the SS blocks are continuous. In some aspects, the symbols of the SS blocks are discontinuous. Similarly, in some aspects, one or more SS blocks of an SS burst may be sent in continuous radio resources (e.g., continuous symbol periods) during one or more time slots. Additionally or alternatively, one or more SS blocks of an SS burst may be sent in discontinuous radio resources.

[0062] In some aspects, an SS burst may have a burst period, whereby a base station may send an SS block of an SS burst according to the burst period. In other words, an SS block may repeat during each SS burst. In some aspects, an SS burst set may have a burst set period, whereby a base station may send an SS burst of an SS burst set according to a fixed burst set period. In other words, an SS burst may repeat during each SS burst set.

[0063] The base station may send system information (e.g., system information blocks (SIBs)) on a physical downlink shared channel (PDSCH) in certain time slots. The base station may send control information / data on a physical downlink control channel (PDCCH) in C symbol periods of a time slot, where B may be configurable for each time slot. The base station may send traffic data and / or other data on the PDSCH in the remaining symbol periods of each time slot.

[0064] As noted above, Figure 3A and 3B is provided as an example. Other examples may differ from those described above. Figure 3A and 3B Examples described.

[0065] Figure 4 An example slot format 410 with a normal cyclic prefix is ​​shown. The available time-frequency resources may be divided into resource blocks. Each resource block may cover a group of subcarriers (e.g., 12 subcarriers) in a slot and may include multiple resource elements. Each resource element may cover one subcarrier in a symbol period (e.g., in units of time) and may be used to send one modulation symbol, which may be real or complex valued.

[0066] The interlaced structure may be used for each of the downlink and uplink for FDD in certain telecommunication systems (e.g., NR). For example, Q interlaces with indices from 0 to Q-1 may be defined, where Q may be equal to 4, 6, 8, 10, or some other value. Each interlace may include time slots spaced apart by Q frames. Specifically, an interlace q may include time slots q, q+Q, q+2Q, etc., where q∈{0,...,Q-1}.

[0067] A UE may be located within the coverage of multiple BSs. One of these BSs may be selected to serve the UE. The serving BS may be selected based at least in part on various criteria (e.g., received signal strength, received signal quality, path loss, etc.). The received signal quality may be quantified by a signal to noise and interference ratio (SNIR), or a reference signal received quality (RSRQ), or some other metric. The UE may operate in a significant interference scenario, where the UE may observe high interference from one or more interfering BSs.

[0068] Although aspects of the examples described herein may be associated with NR or 5G technology, aspects of the present disclosure may be applied with other wireless communication systems. "New Radio" (NR) may refer to a radio configured to operate according to a new air interface (e.g., in addition to an air interface based on Orthogonal Frequency Division Multiple Access (OFDMA)) or a fixed transport layer (e.g., in addition to Internet Protocol (IP)). In various aspects, NR may utilize OFDM with CP (referred to herein as cyclic prefix OFDM or CP-OFDM) and / or SC-FDM on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using time division duplex (TDD). In various aspects, NR may, for example, utilize OFDM with CP (referred to herein as CP-OFDM) and / or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using TDD. NR may include enhanced mobile broadband (eMBB) services targeting wide bandwidth (e.g., 80 megahertz (MHz) and greater), millimeter wave (mmW) targeting high carrier frequencies (e.g., 60 gigahertz (GHz)), massive MTC (mMTC) targeting non-backward compatible MTC technologies, and / or mission critical targeting ultra-reliable low latency communication (URLLC) services.

[0069] In some aspects, a single component carrier bandwidth of 100 MHz may be supported. NR resource blocks may span 12 subcarriers with a subcarrier bandwidth of 60 or 120 kilohertz (kHz) in a 0.1 millisecond (ms) duration. Each radio frame may include 40 slots and may have a length of 10 ms. Thus, each slot may have a length of 0.25 ms. Each slot may indicate a link direction (e.g., DL or UL) for data transmission, and the link direction for each slot may be switched dynamically. Each slot may include DL / UL data and DL / UL control data.

[0070] Beamforming may be supported and the beam direction may be dynamically configured. MIMO transmission with precoding may also be supported. MIMO configuration in DL may support up to 8 transmit antennas with multi-layer DL transmission of up to 8 streams and up to 2 streams per UE. Multi-layer transmission with up to 2 streams per UE may be supported. Aggregation of multiple cells with up to 8 serving cells may be supported. Alternatively, NR may support different air interfaces other than OFDM-based interfaces. NR networks may include entities such as a central unit or a distributed unit.

[0071] As noted above, Figure 4 is provided as an example. Other examples may differ from those described above. Figure 4 Examples described.

[0072] As described above, a UE (or another subordinate wireless communication device) may communicate with another UE on a wireless sidelink in a wireless network. For example, a UE may send one or more sidelink communications to another UE via a sidelink and / or may receive one or more sidelink communications via a sidelink. In addition, a UE may communicate with a BS on a wireless access link in a wireless network. For example, a UE may send uplink communications to a BS on an uplink of an access link, and / or a UE may receive downlink communications from a BS on a downlink of an access link.

[0073] In some cases, the UE may be scheduled to perform access link communications and sidelink communications simultaneously. For example, scheduled access link communications and scheduled sidelink communications may overlap at least partially in the time domain. The scheduling of simultaneous access link communications and sidelink communications may be referred to as a conflict. In some cases, for example, due to hardware and / or software limitations of the UE, the UE may not be able to perform simultaneous access link communications and sidelink communications (e.g., if the access link communications and sidelink communications will occur on the same frequency carrier), and / or may not be able to perform simultaneous access link communications and sidelink communications at full transmit power (e.g., if the access link communications and sidelink communications will occur on different frequency carriers).

[0074] Due to conflicts between access link communications and sidelink communications, the UE may be unable to determine which of the access link communications or the sidelink communications to send and / or receive, may be unable to determine a transmit power distribution for the access link communications and the sidelink communications, etc. This, in turn, may cause the UE to delay or drop urgent or time-sensitive communications and / or high priority channels, may cause delayed or dropped hybrid automatic repeat request (HARQ) retransmissions, may cause phase discontinuity between access link communication transmissions and sidelink communication transmissions, etc.

[0075] Some aspects described herein provide techniques and devices for handling conflicts between access link communications and sidelink communications. In some aspects, the UE may be configured to resolve conflicts between access link communications and sidelink communications based at least in part on corresponding priorities associated with the access link communications and the sidelink communications. In addition, if, for example, the access link communications and the sidelink communications are associated with the same priority, the UE may be configured to resolve conflicts between the access link communications and the sidelink communications based at least in part on other parameters. In this way, the UE can resolve conflicts by determining at least in part based on corresponding priorities and / or other parameters whether to discard access link communications or sidelink communications (and whether to send or receive access link communications or sidelink communications), determining corresponding transmit powers for access link communications and sidelink communications, and the like. This can reduce and / or prevent delays or discards of urgent or time-sensitive communications and / or high priority channels, can reduce and / or prevent delays or discards of HARQ retransmissions, can reduce or prevent phase discontinuities between access link communication transmissions and sidelink communication transmissions, and the like.

[0076] Figure 5 is a diagram of one or more examples 500 of handling conflicts between access link communications and sidelink communications in accordance with various aspects of the present disclosure. Figure 5 As shown, example 500 may include access link communications between a BS (e.g., BS 110) and a UE (e.g., UE 120) and / or sidelink communications between two or more UEs (or other dependent entities).

[0077] In some aspects, a BS and a UE (e.g., UE1, UE2, etc.) may be included in a wireless network (such as wireless network 100 and / or another wireless network). In some aspects, the BS may be a serving BS of UE1 in the wireless network. The BS and UE1 may communicate via a wireless access link, and the wireless access link may be configured with a frame structure (e.g., frame structure 400 and / or another frame structure), a time slot format (e.g., time slot format 510 and / or another time slot format), etc. The access link may include an uplink and a downlink. In some aspects, UE1 and UE2 may communicate via a wireless sidelink. In some aspects, the sidelink may be configured with a frame structure (e.g., frame structure 400 and / or another frame structure), a time slot format (e.g., time slot format 510 and / or another time slot format), etc.

[0078] In some aspects, UE1 may be scheduled by the BS to perform access link communications with the BS. For example, the BS may schedule transmission of downlink communications to UE1 via the access link and / or may schedule uplink transmissions from UE1. The BS may schedule access link communications by sending one or more scheduled communications to UE1. One or more scheduled communications may periodically and / or semi-statically schedule access link communications for UE1 (e.g., one or more radio resource control (RRC) communications, one or more medium access control (MAC) control elements (MAC-CE) communications, etc.), may dynamically schedule access link communications for UE1 (e.g., one or more downlink control information (DCI) communications, etc.), etc.

[0079] In some aspects, similar to access link communication scheduling, UE1 may be scheduled by the BS to perform sidelink communications with UE2. In some aspects, the BS may configure a sidelink resource pool (e.g., time domain resources, frequency domain resources, etc.), and UE1 and / or UE2 may use the sidelink resource pool to autonomously schedule the transmission and / or reception of sidelink communications.

[0080] As in Figure 5 1 and as indicated by reference numeral 502, UE1 may detect a conflict between a scheduled transmission of an uplink communication of the BS and a scheduled transmission of a sidelink communication to UE2. UE1 may detect the conflict based at least in part on determining that the transmission of the uplink communication and the transmission of the sidelink communication at least partially overlap in the time domain. For example, the transmission of the uplink communication and the transmission of the sidelink communication may at least partially overlap in one or more symbols, one or more time slots, one or more subframes, one or more radio frames, etc.

[0081] As in Figure 5 , and as further shown by reference numeral 504, UE1 may send uplink communications and / or sidelink communications based at least in part on detecting a conflict, based at least in part on corresponding priorities associated with the uplink communications and / or channels and the sidelink communications and / or channels. In some aspects, UE1 may consider corresponding priorities of sidelink communications and / or channels and uplink communications and / or channels based at least in part on UE1 being configured with URLLC (e.g., configured with capability 2 timelines of any cell, or if there are parameters that determine a high priority of the channel and are configured).

[0082] In some aspects, UE1 may determine the priority associated with the uplink communication and / or channel based at least in part on the scheduling communication for scheduling the transmission of the uplink communication. For example, the scheduling communication may include one or more bits indicating the priority of the uplink communication and / or channel. In some aspects, the BS may configure the priority of the uplink communication and / or channel at the physical layer, at the MAC layer (for example, in this case, the granularity of the priority may be greater than the case where the priority is generated at the physical layer), or at another communication layer of the BS. If the priority of the uplink communication and / or channel is determined at the physical layer, the priority of the uplink communication and / or channel may be indicated at least in part based on the DCI format / size, the bit field in the DCI, the radio network temporary identifier (RNTI), the search space index, the control resource set (CORESET) index in which the DCI is detected, etc. If the priority of uplink communications and / or channels is MAC-based, the priority of uplink communications and / or channels may be indicated as a result of logical channel (LCH) prioritization (e.g., the priority of a physical uplink shared channel (PUSCH) depends on the LCH index that maps data to the PUSCH)

[0083] In some aspects, UE1 may determine a priority associated with a sidelink communication and / or a channel based at least in part on a scheduling communication that schedules the transmission of the sidelink communication. For example, the scheduling communication may include one or more bits indicating the priority of the sidelink communication and / or the channel. In some aspects, the priority of the sidelink communication and / or the channel may include a ProSe per-packet priority (PPPP) of the sidelink communication and / or the channel, or from the associated sidelink communication when the sidelink communication carries feedback for the associated sidelink communication (e.g., via a physical sidelink feedback channel (PSFCH)).

[0084] In some aspects, the priority associated with uplink communication and / or channel and the priority associated with sidelink communication and / or channel may have different priority granularities. For example, the priority associated with uplink communication and / or channel may be indicated as a value of 0 (e.g., low priority) or a value of 1 (e.g., high priority), while the priority associated with sidelink communication and / or channel may be indicated as 0-10. In this case, UE1 may normalize or convert the priority associated with sidelink communication and / or channel to the granularity of the priority associated with uplink communication and / or channel, may normalize or convert the priority associated with uplink communication and / or channel to the granularity of the priority associated with sidelink communication and / or channel, or may normalize or convert the two priorities to a common granularity. As an example, if the priority associated with the sidelink communication and / or channel is indicated as 0-10 (e.g., PPPP), if the priority satisfies a priority threshold (e.g., a value of 6 or above), UE1 may convert the priority to a value of 1, and if the priority does not satisfy the priority threshold (e.g., a value of 5 or below), UE1 may convert the priority to a value of 0. In some aspects, the priority threshold may be a sidelink priority threshold specified by sl-PriorityThreshold or by another parameter.

[0085] In some aspects, UE1 may resolve conflicts between access link communications (e.g., uplink communication transmission or downlink communication reception) and sidelink communications (e.g., sidelink communication transmission or sidelink communication reception) based at least in part on a sidelink priority threshold. The sidelink priority threshold may or may not be configured. If the sidelink priority threshold is configured and the access link channel or access link communication has a high priority, the sidelink communication priority or the sidelink channel priority is compared with the sidelink priority threshold. If the sidelink priority threshold is not configured and the access link communication or channel has a high priority, the access link communication is maintained and the sidelink communication is discarded. If the access link communication or channel has a low priority and the sidelink priority threshold is configured, the sidelink communication or channel priority is compared with the sidelink priority threshold.

[0086] In some aspects, the priority associated with uplink communication and / or channel and the priority associated with sidelink communication and / or channel may be configured at least in part based on various parameters. For example, the priority associated with uplink communication and / or channel and the priority associated with sidelink communication and / or channel may be configured at least in part based on the communication type associated with uplink communication and the communication type associated with sidelink communication. For example, if the communication is an emergency or time-sensitive communication (such as ultra-reliable low-latency communication (URLLC)) and the other communication is a non-emergency communication (such as enhanced mobile broadband (eMBB) communication), the priority of the communication and / or channel may be higher relative to the priority of the other communication and / or channel. As another example, if the communication carries HARQ feedback and the other communication carries data, the priority of the communication and / or channel may be higher relative to the priority of the other communication and / or channel. In some aspects, when configuring the corresponding priority of the communication, other parameters or combinations thereof may be considered.

[0087] In some aspects, UE1 may determine whether to send uplink communication and / or sidelink communication based at least in part on whether the transmission of uplink communication and the transmission of sidelink communication will occur on the same frequency carrier, the same subcarrier, etc. In some aspects, discarding or avoiding sending sidelink communication or uplink communication may depend on the capabilities of UE1. For example, if UE1 is capable of sending both uplink communication and sidelink communication, UE1 may determine that UE1 does not need to discard either communication. As another example, UE1 may not be able to send communication on the same frequency carrier at the same time, and may determine at least in part based on corresponding priorities whether to send uplink communication or sidelink communication and discard or avoid sending another communication. As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, different subcarriers, etc., the simultaneous transmission of uplink communication and sidelink communication across different frequency carriers may cause phase discontinuity of transmission. In this case, UE1 may determine at least in part based on corresponding priorities whether to suspend the transmission of communication, send another communication at the same time, whether to scale the transmit power used to send communication, and so on.

[0088] As the above example, if the transmission of uplink communication and the transmission of sidelink communication will occur on the same frequency carrier, UE1 can send the sidelink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel is higher than the priority associated with the uplink communication and / or the channel, and discard or avoid sending the uplink communication. As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on the same frequency carrier, UE1 can send the uplink communication based at least in part on determining that the priority associated with the uplink communication and / or the channel is higher than the priority associated with the sidelink communication and / or the channel, and discard or avoid sending the sidelink communication.

[0089] As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may transmit the sidelink communication at a first transmission power greater than the second transmission power at which UE1 transmits the uplink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel is higher relative to the priority associated with the uplink communication and / or the channel. As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may transmit the uplink communication at a first transmission power greater than the second transmission power at which UE1 transmits the sidelink communication based at least in part on determining that the priority associated with the uplink communication and / or the channel is higher relative to the priority associated with the sidelink communication and / or the channel.

[0090] As another example, the first transmit power and the second transmit power may be determined based at least in part on a priority threshold (e.g., a PPPP threshold or another type of sidelink priority threshold) for sidelink communications and / or channels. The sidelink priority threshold may or may not be configured. If the sidelink priority threshold is configured and the access link channel or access link communication has a high priority, the sidelink communication priority or the sidelink channel priority is compared with the sidelink priority threshold. If the sidelink priority threshold is not configured and the access link communication or channel has a high priority, the access link communication may be given a larger transmit power and the sidelink communication may be given a lower transmit power. If the access link communication or channel has a low priority and the sidelink priority threshold is configured, the sidelink communication or channel priority is compared with the sidelink priority threshold.

[0091] As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may temporarily suspend the transmission of uplink communication during the overlapping portion of uplink communication and sidelink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel is higher than the priority associated with the uplink communication and / or the channel in order to send the sidelink communication. As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may temporarily suspend the transmission of sidelink communication during the overlapping portion of uplink communication and sidelink communication based at least in part on determining that the priority associated with the uplink communication and / or the channel is higher than the priority associated with the sidelink communication and / or the channel in order to send the uplink communication.

[0092] As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may determine whether to send one of the communications and discard or avoid sending the other communication based at least in part on the corresponding priority. For example, UE1 may determine the transmit power based on each symbol or each opportunity. In each opportunity, UE1 may determine the total power on all frequency carriers and rescale the power based at least in part on the corresponding priority if necessary. If the total power is lower than Pmax (e.g., total transmit power), UE1 may not need to perform power scaling. Some transmissions may overlap on different frequency carriers, which may produce phase discontinuity when the transmission is sent on a frequency carrier associated with the same power amplifier. When UE1 will transmit on the access link and the sidelink, the BS may know the resources that can be used for the sidelink, but does not know when UE1 will use these resources in some operating modes. Therefore, UE1 sends high priority communications or channels (e.g., across symbols 0 to 13) on the sidelink, and the BS schedules uplink communications for low priority channels (e.g., on symbols 4-5). If UE1 follows the scheduling grant from the BS, the sidelink transmission may lose phase continuity and is unlikely to be successfully decoded. In such a case, even if UE1 is not power limited, UE1 may determine to avoid sending low priority channels in favor of high priority channels.

[0093] In some cases, if UE1 determines that the priority associated with the sidelink communication and / or the channel and the priority associated with the uplink communication and / or the channel are the same priority, UE1 may determine whether to send the uplink communication and / or the sidelink communication based at least in part on one or more configurable rules (e.g., configurable by the BS, UE2 and / or other entities). As an example, if the transmission of the uplink communication and the transmission of the sidelink communication will occur on the same frequency carrier, UE1 may send the sidelink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel and the priority associated with the uplink communication and / or the channel are the same priority, and discard or avoid sending the uplink communication. As another example, if the transmission of the uplink communication and the transmission of the sidelink communication will occur on the same frequency carrier, UE1 may send the uplink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel and the priority associated with the uplink communication and / or the channel are the same priority, and discard or avoid sending the sidelink communication.

[0094] As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may send sidelink communication at a first transmission power based at least in part on determining that the priority associated with the sidelink communication and / or the channel and the priority associated with the uplink communication and / or the channel are the same priority, and may send uplink communication at a second transmission power (e.g., power scaling, in which case the first transmission power may be greater than, less than, or the same as the second transmission power). As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may send uplink communication at a first transmission power based at least in part on determining that the priority associated with the sidelink communication and / or the channel and the priority associated with the uplink communication and / or the channel are the same priority, and may send sidelink communication at a second transmission power (e.g., power scaling, in which case the first transmission power may be greater than, less than, or the same as the second transmission power).

[0095] As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may temporarily suspend the transmission of uplink communication during the overlapping portion of uplink communication and sidelink communication based at least in part on determining that the priority associated with the sidelink communication and / or channel and the priority associated with the uplink communication and / or channel are the same priority in order to send the sidelink communication. As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may temporarily suspend the transmission of sidelink communication during the overlapping portion of uplink communication and sidelink communication based at least in part on determining that the priority associated with the sidelink communication and / or channel and the priority associated with the uplink communication and / or channel are the same priority in order to send the uplink communication.

[0096] In some cases, if UE1 determines that the priority associated with the sidelink communication and / or the channel and the priority associated with the uplink communication and / or the channel are the same priority, UE1 may determine whether to send the uplink communication and / or the sidelink communication based at least in part on one or more configurable parameters (e.g., configurable by the BS, UE2, and / or other entities). The one or more configurable parameters may include the corresponding physical channel types associated with the uplink communication and the sidelink communication, the time domain resources (e.g., symbols, time slots, subframes, radio frames, etc.) and / or frequency domain resources (e.g., frequency carriers, subcarriers, etc.) in which the transmission of the uplink communication overlaps with the transmission of the sidelink communication, the corresponding transmission types associated with the uplink communication and the sidelink communication, and / or other configurable parameters.

[0097] For example, if the transmission of uplink communication and the transmission of sidelink communication are to occur on the same frequency carrier, UE1 may send sidelink communication and discard or avoid sending uplink communication based at least in part on determining that the physical channel type associated with the sidelink communication is PSFCH and the physical channel type associated with the uplink communication is a physical uplink control channel (PUCCH), based at least in part on determining that the physical channel type associated with the sidelink communication is a physical sidelink shared channel (PSSCH) and the physical channel type associated with the uplink communication is PUSCH, and so on. As another example, if the transmission of uplink communication and the transmission of sidelink communication are to occur on the same frequency carrier, UE1 may send uplink communication and discard or avoid sending sidelink communication based at least in part on determining that the physical channel type associated with the uplink communication is a physical random access channel (PRACH) and the physical channel type associated with the sidelink communication is PSFCH, based at least in part on determining that the physical channel type associated with the uplink communication is PUCCH and the physical channel type associated with the sidelink communication is PSSCH, and so on.

[0098] As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may send the sidelink communication at a first transmission power that is greater than a second transmission power at which UE1 sends the uplink communication based at least in part on determining that the physical channel type associated with the sidelink communication is PSFCH and the physical channel type associated with the uplink communication is PUCCH, based at least in part on determining that the physical channel type associated with the sidelink communication is PSSCH and the physical channel type associated with the uplink communication is PUSCH, and so on. As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may send uplink communication at a first transmission power that is greater than a second transmission power at which UE1 sends sidelink communication based at least in part on determining that the physical channel type associated with the uplink communication is PRACH and the physical channel type associated with the sidelink communication is PSFCH, based at least in part on determining that the physical channel type associated with the uplink communication is PUCCH and the physical channel type associated with the sidelink communication is PSSCH, and so on.

[0099] As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may temporarily suspend the transmission of uplink communication during the overlapping portion of the uplink communication and the sidelink communication in order to send the sidelink communication based at least in part on determining that the physical channel type associated with the sidelink communication is PSFCH and the physical channel type associated with the uplink communication is PUCCH, based at least in part on determining that the physical channel type associated with the sidelink communication is PSSCH and the physical channel type associated with the uplink communication is PUSCH, and so on. As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may temporarily suspend the transmission of sidelink communication during the overlapping portion of the uplink communication and the sidelink communication in order to send the uplink communication based at least in part on determining that the physical channel type associated with the uplink communication is PRACH and the physical channel type associated with the sidelink communication is PSFCH, based at least in part on determining that the physical channel type associated with the uplink communication is PUCCH and the physical channel type associated with the sidelink communication is PSSCH, and so on.

[0100] As another example, if the transmission of the uplink communication and the transmission of the sidelink communication will occur on the same frequency carrier, UE1 may send the sidelink communication and discard or avoid sending the uplink communication based at least in part on determining that the transmission type associated with the sidelink communication is broadcast, groupcast, or multicast. As another example, if the transmission of the uplink communication and the transmission of the sidelink communication will occur on the same frequency carrier, UE1 may send the uplink communication and discard or avoid sending the sidelink communication based at least in part on determining that the transmission type associated with the sidelink communication is unicast.

[0101] As another example, if the transmission of uplink communications and the transmission of sidelink communications will occur on different frequency carriers, UE1 may transmit the sidelink communications at a first transmission power greater than the second transmission power at which UE1 transmits the uplink communications based at least in part on determining that the transmission type associated with the sidelink communications is broadcast, groupcast, or multicast. As another example, if the transmission of uplink communications and the transmission of sidelink communications will occur on different frequency carriers, UE1 may transmit the uplink communications at a first transmission power greater than the second transmission power at which UE1 transmits the sidelink communications based at least in part on determining that the transmission type associated with the sidelink communications is unicast.

[0102] As another example, if the transmission of the uplink communication and the transmission of the sidelink communication will occur on different frequency carriers, UE1 may temporarily suspend the transmission of the uplink communication during the overlapping portion of the uplink communication and the sidelink communication based at least in part on determining that the transmission type associated with the sidelink communication is broadcast, groupcast, or multicast in order to send the sidelink communication. As another example, if the transmission of the uplink communication and the transmission of the sidelink communication will occur on different frequency carriers, UE1 may temporarily suspend the transmission of the sidelink communication during the overlapping portion of the uplink communication and the sidelink communication based at least in part on determining that the transmission type associated with the sidelink communication is unicast in order to send the uplink communication.

[0103] As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on the same frequency carrier, UE1 may send the sidelink communication and discard or avoid sending the uplink communication based at least in part on determining that the time domain resources in which the transmission of the sidelink communication and the transmission of the uplink communication overlap are scheduled for sidelink retransmission (e.g., HARQ retransmission), are prioritized for sidelink communication, etc. As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on the same frequency carrier, UE1 may send the uplink communication and discard or avoid sending the sidelink communication based at least in part on determining that the time domain resources in which the transmission of the sidelink communication and the transmission of the uplink communication overlap are not scheduled for sidelink retransmission, are prioritized for uplink communication, etc.

[0104] As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may transmit the sidelink communication at a first transmission power that is greater than the second transmission power at which UE1 transmits the uplink communication based at least in part on determining that time domain resources in which the transmission of sidelink communication and the transmission of uplink communication overlap are scheduled for sidelink retransmission, are prioritized for sidelink communication, etc. As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may transmit the uplink communication at a first transmission power that is greater than the second transmission power at which UE1 transmits the sidelink communication based at least in part on determining that time domain resources in which the transmission of sidelink communication and the transmission of uplink communication overlap are not scheduled for sidelink retransmission, are prioritized for uplink communication, etc.

[0105] As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may temporarily suspend the transmission of uplink communication during the overlapping portion of uplink communication and sidelink communication based at least in part on determining that the time domain resources in which the transmission of sidelink communication and the transmission of uplink communication overlap are scheduled for sidelink retransmission, are prioritized for sidelink communication, etc., in order to send the sidelink communication. As another example, if the transmission of uplink communication and the transmission of sidelink communication will occur on different frequency carriers, UE1 may temporarily suspend the transmission of sidelink communication during the overlapping portion of uplink communication and sidelink communication based at least in part on determining that the time domain resources in which the transmission of sidelink communication and the transmission of uplink communication overlap are not scheduled for sidelink retransmission, are prioritized for uplink communication, etc., in order to send the uplink communication.

[0106] In some aspects, UE1 may revert to LTE parameters or rules to determine whether to send uplink communications and / or sidelink communications, in which case UE1 may determine whether to send uplink communications and / or sidelink communications based at least in part on priorities associated with the sidelink communications and / or channels. This may occur, for example, in situations where urgent or time-sensitive communications sent by the UE are not scheduled.

[0107] In this way, the UE (e.g., UE1) can be configured to resolve the conflict between the access link communication and the side link communication based at least in part on the corresponding priorities associated with the access link communication and the side link communication. In addition, if, for example, the access link communication and / or the channel and the side link communication and / or the channel are associated with the same priority, the UE can be configured to resolve the conflict between the access link communication and the side link communication based at least in part on other parameters. In this way, the UE can resolve the conflict by determining whether to discard the access link communication or the side link communication (and whether to send or receive the access link communication or the side link communication), determining the corresponding transmit power for the access link communication and the side link communication, and / or at least in part based on the corresponding priorities and / or other parameters, etc. This can reduce and / or prevent delayed or discarded urgent or time-sensitive communications and / or high priority channels, can reduce and / or prevent delayed or discarded HARQ retransmissions, can reduce or prevent phase discontinuity between access link communication transmissions and side link communication transmissions, and the like.

[0108] As noted above, Figure 5 is provided as one or more examples. Other examples may differ from Figure 5 Examples described.

[0109] Figure 6 6 is a diagram of one or more examples 600 of handling conflicts between access link communications and sidelink communications in accordance with various aspects of the present disclosure. Figure 6 As shown, example 600 may include access link communications between BS and UE1 and / or side link communications between UE1 and UE2.

[0110] As in Figure 6 1 and as indicated by reference numeral 602, UE1 may detect a conflict between a scheduled reception of a downlink communication from a BS and a scheduled reception of a sidelink communication from UE2. UE1 may detect the conflict based at least in part on determining that the reception of the downlink communication and the reception of the sidelink communication at least partially overlap in the time domain. For example, the reception of the downlink communication and the reception of the sidelink communication may at least partially overlap in one or more symbols, one or more time slots, one or more subframes, one or more radio frames, etc.

[0111] As in Figure 6 In the embodiment and as further shown by reference numeral 604, UE1 may receive the downlink communication or the sidelink communication based at least in part on the detection of the conflict and at least in part on the respective priorities associated with the downlink communication and the sidelink communication. In some aspects, UE1 may receive the downlink communication or the sidelink communication based at least in part on the detection of the conflict and at least in part on the respective priorities associated with the downlink communication and the sidelink communication. Figure 5 One or more techniques described herein are used to determine priorities associated with downlink communications and / or channels and priorities associated with sidelink communications and / or channels. In some aspects, UE1 may consider the respective priorities of sidelink communications and / or channels and downlink communications and / or channels based at least in part on UE1 being configured with URLLC (e.g., configured with capability 2 timelines of any cell, or if there are parameters that determine a high priority for a channel and are configured).

[0112] In some aspects, UE1 may determine whether to receive downlink communications or sidelink communications based at least in part on whether the reception of downlink communications and the reception of sidelink communications will occur on the same frequency carrier, the same subcarrier, etc. In some aspects, discarding or avoiding receiving sidelink communications or downlink communications may depend on the capabilities of UE1. For example, if UE1 is capable of receiving both downlink communications and sidelink communications, UE1 may determine that UE1 does not need to discard either communication. As another example, UE1 may not be able to receive and process communications on the same frequency carrier at the same time, and may determine whether to receive downlink communications or sidelink communications and discard or avoid receiving another communication based at least in part on corresponding priorities. For example, UE1 may receive sidelink communications and discard or avoid receiving downlink communications based at least in part on determining that the priority associated with the sidelink communication and / or the channel is higher than the priority associated with the downlink communication and / or the channel. As another example, UE1 may receive downlink communications and discard or avoid receiving sidelink communications based at least in part on determining that the priority associated with downlink communications and / or channels is higher than the priority associated with sidelink communications and / or channels.

[0113] In some cases, if UE1 determines that the priority associated with the sidelink communication and / or the channel and the priority associated with the downlink communication and / or the channel are the same priority, UE1 may determine whether to receive the downlink communication or the sidelink communication based at least in part on one or more configurable rules (e.g., configurable by the BS, UE2, and / or other entities). For example, UE1 may receive the sidelink communication and discard or avoid receiving the downlink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel and the priority associated with the downlink communication and / or the channel are the same priority. As another example, UE1 may receive the downlink communication and discard or avoid receiving the sidelink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel and the priority associated with the downlink communication and / or the channel are the same priority.

[0114] In some cases, if UE1 determines that the priority associated with the sidelink communication and / or the channel and the priority associated with the downlink communication and / or the channel are the same priority, UE1 may determine whether to receive the downlink communication or the sidelink communication based at least in part on one or more configurable parameters (e.g., configurable by the BS, UE2, and / or other entities). The one or more configurable parameters may include the corresponding physical channel types associated with the downlink communication and the sidelink communication, the time domain resources and / or frequency domain resources in which the reception of the downlink communication overlaps with the reception of the sidelink communication, the corresponding transmission types associated with the downlink communication and the sidelink communication, and / or other configurable parameters.

[0115] As an example, UE1 may receive sidelink communications and discard or avoid receiving downlink communications based at least in part on determining that the physical channel type associated with the sidelink communications is PSFCH and the physical channel type associated with the downlink communications is a physical downlink control channel (PDCCH), based at least in part on determining that the physical channel type associated with the sidelink communications is PSSCH and the physical channel type associated with the downlink communications is a physical downlink shared channel (PDSCH), etc. As another example, UE1 may receive downlink communications and discard or avoid receiving sidelink communications based at least in part on determining that the physical channel type associated with the downlink communications is PRACH and the physical channel type associated with the sidelink communications is PSFCH, based at least in part on determining that the physical channel type associated with the downlink communications is PDCCH and the physical channel type associated with the sidelink communications is PSSCH, etc.

[0116] As another example, UE1 may receive sidelink communications and discard or refrain from receiving downlink communications based at least in part on determining that the transmission type associated with the sidelink communications is broadcast, groupcast, or multicast. As another example, UE1 may receive downlink communications and discard or refrain from receiving sidelink communications based at least in part on determining that the transmission type associated with the sidelink communications is unicast.

[0117] As another example, UE1 may receive sidelink communications and discard or avoid receiving downlink communications based at least in part on determining that time domain resources in which reception of sidelink communications and reception of downlink communications overlap are scheduled for sidelink retransmissions, are prioritized for sidelink communications, etc. As another example, UE1 may receive downlink communications and discard or avoid receiving sidelink communications based at least in part on determining that time domain resources in which reception of sidelink communications and reception of downlink communications overlap are not scheduled for sidelink retransmissions, are prioritized for downlink communications, etc.

[0118] As noted above, Figure 6 is provided as one or more examples. Other examples may differ from Figure 6 Examples described.

[0119] Figure 7 7 is a diagram of one or more examples 700 of handling conflicts between access link communications and sidelink communications in accordance with various aspects of the present disclosure. Figure 7 As shown, example 700 may include access link communications between BS and UE1 and / or side link communications between UE1 and UE2.

[0120] As in Figure 7 1 and as indicated by reference numeral 702, UE1 may detect a conflict between a scheduled transmission of an uplink communication of the BS and a scheduled reception of a sidelink communication from UE2. UE1 may detect the conflict based at least in part on determining that the transmission of the uplink communication and the reception of the sidelink communication at least partially overlap in the time domain. For example, the transmission of the uplink communication and the reception of the sidelink communication may at least partially overlap in one or more symbols, one or more time slots, one or more subframes, one or more radio frames, etc.

[0121] As in Figure 7 In the embodiment and as further shown by reference numeral 704, UE1 may send uplink communication or receive sidelink communication based at least in part on detecting the conflict and at least in part on the respective priorities associated with the uplink communication and the sidelink communication. In some aspects, UE1 may send uplink communication or receive sidelink communication based at least in part on the detection of the conflict. Figure 5 One or more techniques described herein determine priorities associated with uplink communications and / or channels and priorities associated with sidelink communications and / or channels. In some aspects, UE1 may consider the corresponding priorities of sidelink communications and / or channels and uplink communications and / or channels based at least in part on UE1 being configured with URLLC (e.g., configured with capability 2 timelines of any cell, or if there are parameters that determine a high priority for a channel and are configured).

[0122] In some aspects, UE1 may determine whether to send uplink communication or receive sidelink communication based at least in part on whether the transmission of uplink communication and the reception of sidelink communication will occur on the same frequency carrier, the same subcarrier, etc. In some aspects, discarding or avoiding receiving sidelink communication or discarding or avoiding sending uplink communication may depend on the capabilities of UE1. For example, if UE1 is able to send uplink communication and receive sidelink communication, UE1 may determine that UE1 does not need to discard either communication. As another example, UE1 may not be able to send and receive multiple communications on the same frequency carrier at the same time, and may determine whether to send uplink communication or receive sidelink communication and discard or avoid sending or receiving another communication based at least in part on the corresponding priority. For example, UE1 may receive sidelink communication and discard or avoid sending uplink communication based at least in part on determining that the priority associated with sidelink communication and / or channel is higher than the priority associated with uplink communication and / or channel. As another example, UE1 may send uplink communications and discard or avoid receiving sidelink communications based at least in part on determining that a priority associated with uplink communications and / or channels is higher than a priority associated with sidelink communications and / or channels. As another example, if a downlink symbol is indicated as available for sidelink transmission, then if there is a downlink communication scheduled on the access link and UE1 will send the sidelink communication on the sidelink on the same symbol, the access link may have a higher priority.

[0123] In some cases, if UE1 determines that the priority associated with the sidelink communication and / or the channel and the priority associated with the uplink communication and / or the channel are the same priority, UE1 may determine whether to send uplink communication or receive sidelink communication based at least in part on one or more configurable rules (e.g., configurable by BS, UE2 and / or other entities). For example, UE1 may receive sidelink communication and discard or avoid sending uplink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel and the priority associated with the uplink communication and / or the channel are the same priority. As another example, UE1 may send uplink communication and discard or avoid receiving sidelink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel and the priority associated with the uplink communication and / or the channel are the same priority.

[0124] In some cases, if UE1 determines that the priority associated with the sidelink communication and / or the channel and the priority associated with the uplink communication and / or the channel are the same priority, UE1 may determine whether to send the uplink communication or receive the sidelink communication based at least in part on one or more configurable parameters (e.g., configurable by the BS, UE2, and / or other entities). The one or more configurable parameters may include the corresponding physical channel types associated with the uplink communication and the sidelink communication, the time domain resources and / or frequency domain resources in which the transmission of the uplink communication and the reception of the sidelink communication overlap, the corresponding transmission types associated with the uplink communication and the sidelink communication, and / or other configurable parameters.

[0125] As an example, UE1 may receive sidelink communications and discard or avoid sending uplink communications based at least in part on determining that the physical channel type associated with the sidelink communications is PSFCH and the physical channel type associated with the uplink communications is PUCCH, based at least in part on determining that the physical channel type associated with the sidelink communications is PSSCH and the physical channel type associated with the uplink communications is PUSCH, and so on. As another example, UE1 may send uplink communications and discard or avoid receiving sidelink communications based at least in part on determining that the physical channel type associated with the uplink communications is PRACH and the physical channel type associated with the sidelink communications is PSFCH, based at least in part on determining that the physical channel type associated with the uplink communications is PUCCH and the physical channel type associated with the sidelink communications is PSSCH, and so on.

[0126] As another example, UE1 may receive sidelink communications and discard or refrain from sending uplink communications based at least in part on determining that the transmission type associated with the sidelink communications is broadcast, groupcast, or multicast. As another example, UE1 may send uplink communications and discard or refrain from receiving sidelink communications based at least in part on determining that the transmission type associated with the sidelink communications is unicast.

[0127] As another example, UE1 may receive sidelink communications and discard or avoid sending uplink communications based at least in part on determining that time domain resources in which reception of sidelink communications and transmission of uplink communications overlap are scheduled for sidelink retransmission, are prioritized for sidelink communications, etc. As another example, UE1 may send uplink communications and discard or avoid receiving sidelink communications based at least in part on determining that time domain resources in which reception of sidelink communications and transmission of uplink communications overlap are not scheduled for sidelink retransmission, are prioritized for uplink communications, etc.

[0128] As noted above, Figure 7 is provided as one or more examples. Other examples may differ from Figure 7 Examples described.

[0129] Figure 8 8 is a diagram of one or more examples 800 of handling conflicts between access link communications and sidelink communications in accordance with various aspects of the present disclosure. Figure 8 As shown, example 800 may include access link communications between BS and UE1 and / or side link communications between UE1 and UE2.

[0130] As in Figure 8 8 and as indicated by reference numeral 802, UE1 may detect a conflict between a scheduled reception of a downlink communication from a BS and a scheduled transmission of a sidelink communication to UE2. UE1 may detect the conflict based at least in part on determining that the reception of the downlink communication and the transmission of the sidelink communication at least partially overlap in the time domain. For example, the reception of the downlink communication and the transmission of the sidelink communication may at least partially overlap in one or more symbols, one or more time slots, one or more subframes, one or more radio frames, etc.

[0131] As in Figure 8 In the embodiment and further illustrated by reference numeral 804, UE1 may receive downlink communication or send sidelink communication based at least in part on detecting a conflict and based at least in part on respective priorities associated with the downlink communication and the sidelink communication. In some aspects, UE1 may receive downlink communication or send sidelink communication based at least in part on the above in combination with Figure 5 One or more techniques described herein are used to determine priorities associated with downlink communications and / or channels and priorities associated with sidelink communications and / or channels. In some aspects, UE1 may consider the respective priorities of sidelink communications and / or channels and downlink communications and / or channels based at least in part on UE1 being configured with URLLC (e.g., configured with capability 2 timelines of any cell, or if there are parameters that determine a high priority for a channel and are configured).

[0132] In some aspects, UE1 may determine whether to receive downlink communication or sidelink communication based at least in part on whether the reception of downlink communication and the reception of sidelink communication will occur on the same frequency carrier, the same subcarrier, etc. In some aspects, discarding or avoiding sending sidelink communication or discarding or avoiding receiving downlink communication may depend on the capabilities of UE1. For example, if UE1 is able to send sidelink communication and receive downlink communication, UE1 may determine that UE1 does not need to discard either communication. As another example, UE1 may not be able to receive and send multiple communications on the same frequency carrier at the same time, and may determine whether to receive downlink communication or send sidelink communication and discard or avoid receiving or sending another communication based at least in part on the corresponding priorities. For example, UE1 may send sidelink communication and discard or avoid receiving downlink communication based at least in part on determining that the priority associated with the sidelink communication and / or channel is higher than the priority associated with the downlink communication and / or channel. As another example, UE1 may receive downlink communications and discard or refrain from sending sidelink communications based at least in part on determining that priorities associated with downlink communications and / or channels are higher than priorities associated with sidelink communications and / or channels.

[0133] In some cases, if UE1 determines that the priority associated with the sidelink communication and / or the channel and the priority associated with the downlink communication and / or the channel are the same priority, UE1 may determine whether to receive the downlink communication or send the sidelink communication based at least in part on one or more configurable rules (e.g., configurable by the BS, UE2 and / or other entities). For example, UE1 may send the sidelink communication and discard or avoid receiving the downlink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel and the priority associated with the downlink communication and / or the channel are the same priority. As another example, UE1 may receive the downlink communication and discard or avoid sending the sidelink communication based at least in part on determining that the priority associated with the sidelink communication and / or the channel and the priority associated with the downlink communication and / or the channel are the same priority.

[0134] In some cases, if UE1 determines that the priority associated with the sidelink communication and / or the channel and the priority associated with the downlink communication and / or the channel are the same priority, UE1 may determine whether to receive the downlink communication or the sidelink communication based at least in part on one or more configurable parameters (e.g., configurable by the BS, UE2, and / or other entities). The one or more configurable parameters may include the corresponding physical channel types associated with the downlink communication and the sidelink communication, the time domain resources and / or frequency domain resources in which the reception of the downlink communication overlaps with the transmission of the sidelink communication, the corresponding transmission types associated with the downlink communication and the sidelink communication, and / or other configurable parameters.

[0135] As an example, UE1 may send sidelink communications and discard or avoid receiving downlink communications based at least in part on determining that the physical channel type associated with the sidelink communication is PSFCH and the physical channel type associated with the downlink communication is PDCCH, based at least in part on determining that the physical channel type associated with the sidelink communication is PSSCH and the physical channel type associated with the downlink communication is PDSCH, and so on. As another example, UE1 may receive downlink communications and discard or avoid sending sidelink communications based at least in part on determining that the physical channel type associated with the downlink communication is PRACH and the physical channel type associated with the sidelink communication is PSFCH, based at least in part on determining that the physical channel type associated with the downlink communication is PDCCH and the physical channel type associated with the sidelink communication is PSSCH, and so on.

[0136] As another example, UE1 may receive sidelink communications and discard or refrain from receiving downlink communications based at least in part on determining that the transmission type associated with the sidelink communications is broadcast, groupcast, or multicast. As another example, UE1 may receive downlink communications and discard or refrain from receiving sidelink communications based at least in part on determining that the transmission type associated with the sidelink communications is unicast.

[0137] As another example, UE1 may receive sidelink communications and discard or avoid receiving downlink communications based at least in part on determining that time domain resources in which transmission of sidelink communications and reception of downlink communications overlap are scheduled for sidelink retransmissions, are prioritized for sidelink communications, etc. As another example, UE1 may receive downlink communications and discard or avoid sending sidelink communications based at least in part on determining that time domain resources in which transmission of sidelink communications and reception of downlink communications overlap are not scheduled for sidelink retransmissions, are prioritized for downlink communications, etc.

[0138] As noted above, Figure 8 is provided as one or more examples. Other examples may differ from Figure 8 Examples described.

[0139] Fig. 9 9 is a diagram illustrating an example process 900 performed, for example, by a UE in accordance with various aspects of the present disclosure. Example process 900 is an example of operations in which a UE (eg, UE 120) performs operations associated with handling conflicts between access link communications and sidelink communications.

[0140] like Fig. 9 As shown, in some aspects, process 900 may include detecting a collision between a transmission of an uplink communication associated with the UE and a transmission of a sidelink communication associated with the UE (block 910). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may detect a collision between a transmission of an uplink communication associated with the UE and a transmission of a sidelink communication associated with the UE, as described above.

[0141] like Fig. 9 As further shown, in some aspects, process 900 may include sending at least one of the uplink communication or the sidelink communication based at least in part on detecting the conflict, based at least in part on a priority associated with the uplink communication and a priority associated with the sidelink communication (block 920). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may send at least one of the uplink communication or the sidelink communication based at least in part on detecting the conflict, based at least in part on a priority associated with the uplink communication and a priority associated with the sidelink communication, as described above.

[0142] Process 900 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0143] In a first aspect, detecting a conflict includes: determining that a transmission of an uplink communication and a transmission of a sidelink communication will occur on the same frequency carrier; and determining that the transmission of the uplink communication and the transmission of the sidelink communication overlap at least partially in the time domain. In a second aspect, either alone or in combination with the first aspect, process 900 also includes: determining that a priority associated with the sidelink communication is higher relative to a priority associated with the uplink communication, and sending at least one of the uplink communication or the sidelink communication includes: sending the sidelink communication based at least in part on determining that the priority associated with the sidelink communication is higher relative to the priority associated with the uplink communication.

In a fourth aspect, either alone or in combination with one or more of the first to third aspects, process 900 further includes: determining that a priority associated with uplink communication and a priority associated with sidelink communication are the same priority, and sending at least one of the uplink communication or the sidelink communication includes: sending the sidelink communication based at least in part on determining that the priority associated with uplink communication and the priority associated with sidelink communication are the same priority.

[0145] In the fifth aspect, alone or in combination with one or more of the first to fourth aspects, process 900 also includes: determining that the priority associated with the uplink communication and the priority associated with the sidelink communication are the same priority, and sending at least one of the uplink communication or the sidelink communication includes: sending the uplink communication based at least in part on determining that the priority associated with the uplink communication and the priority associated with the sidelink communication are the same priority.
